###### *Q*: My chars with accents in HTML document are not correctly rendered.

*A*: Make sure that you have set `<meta charset="UTF-8" />`

###### *Q*: My chars with accents passed to wkhtmltopdf options are not correctly rendered, i.e. `footer-right => 'Página [page] de [toPage]'` is converted to 'Página 1 de 1'.

*A*: The answer is long here. We use `escapeshellarg` (and Symfony/Process as well) function to escape all the option value passed to `wkhtmltox`. `escapeshellarg` makes its escape based on server locale, so if you are experiencing this issue - you can set
```php
setlocale(LC_CTYPE, 'es_ES.UTF-8')
```

or any locale which is suitable for you. You should take into account that if given locale is not configured on the server - you will still have an issue. Check your locales installed via running
```bash
locale -a
```
If the needed locale is missing on the server - you should install/configure it.
